It is implicated in a number of diseases as well, including cervical cancer caused by the human papilloma virus. Because it is involved in the body's inflammatory response to invading microbes, it ma...

...ise to the different types of blood cells. Unlike embryonic stem cells, HSCs have already taken some steps in differentiation and are committed to producing various types of blood cells. "This is a wonderful model system," Singh said. "We know more about the differentiation of B cells and red cells than othe...

The federal government provides funding for human embryonic stem cell research only to scientists working on approved lines of pre-existing stem cells. Privately funded researchers at many businesses and academic institutions, however, are pursuing studies on stem cells derived from donated embryos and not in...

She is now a postdoctoral fellow in Dr. Sally Temple's laboratory working on mechanisms regulating neural stem cell self-renewal and cell fate choices, including interactions between neural stem cells and endothelial niche cel...

... 1-phosphate receptor 1 (S1P1), is required during embryonic development to stabilize new blood vessels. Timothy Hla and colleagues, from the University of Connecticut Health Science Center, inves-tigated the importance of S1P1 in angiogenesis in tumors. The authors implanted mice with Lewis lung carcinoma cel...

By 7 days old, the expression of proteins normally found in cartilage was reduced, although at this stage the kne...

...n-base-pair mouse genome were deleted. To do this, embryonic cells were genetically engineered to contain the newly compact mouse genome. Mice were subsequently generated from these stem cells. The research team then compared the resulting mice with the abridged genome to mice with the full-length version. A...

These stem cells were then used to create chimeras -- animals whose make-up comes partially from their original cells and partially from the inserted, engineer...
